Gday to all you R32 guys...

I have an R32 GTST and after say 10mins of highway driving at say 70km/h+ my car feels as if it loses its rear grip for a half and instant - scary stuff. My HICAS light then comes on.

I have deduced with the help of my new mechanic that it is the HICAS system changing the steering direction of the rear wheels. When you first start up the car apparently the rear wheels steer in the opposite direction to the front but after several minutes of driving they revert to the same direction as the fronts / / to / /

/ /

if you know what i mean...

My question is... does your R32 suffer this herendous and sh#t scary tail wag as it changes??? When i say scary i mean drift style sideways (so it seems)...

Your feedback is much appreciated...

Mine's fine, never had any probs with it in the last 14 months. My hicas light used to come on but it was caused by a leak in the power steering pump. The light is only a warning to tell u if its not working. The hicas only moves the rear wheels something like 1.5deg either way depending on speed. Hope this helps :D

Mine does the same thing. I have almost taken out cars when you get caught in rydges in the road. Bloody scary.

My hicas light is on and my steering has gone heavy. I think it might be the power steering solenoid down near the rack.

Let me know if you sought it out.

Doc

Cheers guys...

yeah Doc, that's it - it goes really heavy and sometimes my car actually stalls if it occurs at slow speed.

I remember now that my mechanic said it had something to do with the aftermarket steering wheel i have because the sensor is apparently linked at the steering wheel and when they fit an aftermarket jobby it screws up the system somehow.....

Haven't had any problems with my HICAS on the hwy. Did save me from a great mess once though when I saw a turnoff too late and hooked it hard left at (undisclosed)km/h.... Instead of sliding off the road and into that big tree...I was carried merrily on my way & into the corner - felt bloddy wierd!

When I first start the car, I have to turn a left & right a little before the steering becomes light again.

Also If I idle the car for too long the HICAS light comes on. I've tried running the diagnostic, but it wouldn't work :confused:

MY R32 gtst won't show the hicas light at all. Full stop. There is no light from what I've seen. It seems to turn o.k, but i've NFI if the 4ws is actually working or not. The computer is still plugged in under the rear parcel shelf, the rack is still there, all of the hydraulic lines are still there... I dunno?

mine isnt really disabled properly it just doesnt work lol

im waiting for Dr-Drift to come over with my pineapples so i can pull the plug on the hicas and disable it properlly... but if u ask me... its a hell of a lot better... i hate how it pulls to certain sides when driving before it stops working... even before i stuffed it i hated the feeling it gave when turning.

Had the same problem and took it to givin wood on the gold coast.

The problem was the steering selector for the hicas.

It seems that there are two types and on one the selector is at 38 degrees so that at speed the thinks it is in a permanent left turn. this problem is only fixed with the correct part or by a hicas lock kit.

I've never had any issues..

Just a question for all those who are saying that they have a hard to turn steering... have you checked the power steering fluid recently?

Have you changed it at all?

As for the drift pineapples... they do not do anything for the HICAS. I believe that they are simply for stopping axle tramp, and allowing you to set your car to drift a bit more stable.

The only way to disable HICAS on our R32's is to get a proper lock kit.

You can't just disconnect the computer cause that means that the rear is then able to turn 1.5 degrees in any direction the road drags it.. NOW THAT would be scary.

When your HICAS is working properly, it only works when you are traveling above 80kms. And it ONLY works to turn the rear wheels in the SAME direction as the front to make lane changing on the highways, a smoother process.

So this thing about your mechanic telling you that it turns opposite at low speeds and same at high speeds is false.

    • That was the first session so not a lot to take from the day. It was low 20s ambient and the coolant had got to 110 (and obviously had some pressure!) so that still needs to be addressed. I haven't downloaded the data yet but will. I had refilled the auto trans with Redline DT6 because it claimed the best viscosity I could find at 100o. It wasn't really long enough to get a good feel for that; while the trans got to 100o in the session it still wasn't shifting crisply as I hoped. I think I'll try a few more sessions before judging. No steering motor overheat but I'd hope not in only 1 session! But finally the suspension; it was night and day over the standard stuff and the car was a couple of seconds quicker on the same crappy tyres, which is a huge difference. I'll stick with that and get some sway bars and a mechanical diff sorted too and see how that all goes together
    • I guess it’s partially a compromise of how my car is used, wanting to be able to switch from drift to grip with track side on-car adjustment. Also partially with the way the knuckles are set there is more static camber but less dynamic camber gain. 
    • OK, so update from the track day on Friday It was a classic "an unfortunate series of events'. There were a few cars around and when i checked my mirror coming out of the fish hook I notice some smoke from the rear of mine. Looked again and it was getting much worse, I figured I'd blown a turbo or something to got off it and pulled off the racing line. However.... since it is a left hairpin into a right kink, I was on the inside of the next corner. There was a car passing me on the left and a big drop off over the ripple strip on the right......and someone had knocked the witch's hat that was on the apex about 1m onto the track. So, between those 3, I decided to mow down the cone and not damage my car/the other car. Right choice, but surprising result.  The car decided the cone was a small pedestrian so it blew the rear bonnet hinges up to protect their head in the upcoming person to car impact....I didn't see that coming and like an airbag deployment it happened super fast. Straight into the pits from there, everything was driving fine but it became clear it was a coolant leak not smoke, it was billowing up onto the windscreen. Onto the trailer and home. I'll do a separate thread about the repair (once I work out what it is ), but the immediate problem was the bonnet wouldn't open because the front was pinched onto the front bar and would not release. Ultimately we unbolted the hinge from the bonnet, pulled it back a little and it released from the front OK. "There's your problem", the top radiator hose had popped off at the radiator.
    • Yeah that looks like great caster, but I'd suggest trying less front camber some time and seeing if it helps with braking without reducing mid corner speed too much
    • I ended up setting the rear 5mm higher than normal to give some clearance.  My plan is to run the least camber I can in the rear which I think with the extra width is going to need to be -1.75 to -2.00° just to get clearance.  Guards have been rolled and pulled as much as they can/I would be wanting to.  front has the Acostal knuckle with the KPI change and the drop etc. So should be okay with the existing settings I have run with AR1s etc Front: Toe total -2mm(1mm out each side) Caster +7.5° Camber -3.8° Ackerman +15°
